Abstract

The World Wide Web is becoming increasingly personalized as users provide more of their information on the Web. Thus, Web service functionality is becoming reliant on user pro le information and context in order to provide user-speci c data. In this paper, we discuss enhancements to SECE (Sense Everything, Control Everything), a platform for context-aware service composition based on user-de ned rules. We have enhanced SECE to interpret ontology descriptions of services. With this enhancement, SECE can now create user-de ned rules based on the ontology description of the service and interoperate within any service domain that has an ontology description. Additionally, it can use an ontology-based service discovery system like GloServ as its service
discovery back-end in order to issue more complex queries for service discovery and composition. This paper discusses the design and implementation of these improvements.
